Dag Lem a32d9b6c45 Fix test of memory vs. memory converted to registers 
The purpose of memtest02 in tests/simple/memory.v is to	test bit
select on both memory (mem1) and memory converted to registers (mem2).

After 7cfae2c52, mem1 was automatically converted to registers,
and the test no longer worked as intended. This is fixed by
adding (* nomem2reg *) to mem1.

Thomas Watson b1f8308772 tests/various/clk2fflogic_effects.sh: fix tail invocation 
Previous syntax is a GNU extension and not accepted by macOS. Use
documented -n option instead, compatible with POSIX-compliant tail
implementations.

Catherine 1236bb65b6 read_verilog: don't include empty `opt_sva_label` in span. 
Consider this SystemVerilog file:

    module top(...);
      input clk;
      input [7:0] data;
      input ack;

      always @(posedge clk)
        if (ack) begin
          assert(data != 8'h0a);
        end
    endmodule

Before this commit, the span for the assert was:

        if (ack) begin>
          assert(data != 8'h0a)<;

After this commit, the span for the assert is:

        if (ack) begin
          >assert(data != 8'h0a)<;

This helps editor integrations that only look at the beginning
of the span.

Jannis Harder 10d5d358d2 Ignore $scopeinfo in write_aiger 
While SBY's aiger flow already removes non-assertion driving logic,
there are some uses of write_aiger outside of SBY that could end up with
$scopeinfo cells, so we explicitly ignore them.

The write_btor backend works differently and due to the way it
recursively visits cells, it would never reach isolated cells like
$scopeinfo.

Jannis Harder 0470cbb00d hierarchy: Without a known top module, derive all deferred modules 
This fixes hierarchy when used with cell libraries that were loaded with
-defer and also makes more of the hierarchy visible to the auto-top
heuristic.
